TRUCK SIDE FRAME.

Application filed March 18, 1909.

To ett whom 'it may concern:

Be it known that I, Joux II. l't'ICConMICK, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Truck Side Frames, of which the following is a specification.

My invention relates to the improvement of truck side frames for cars, and the objects of my invention are to provide an improved side frame having maximum strength and minimum weight; to construct my improved side frame of comparatively few parts and of such arrangement as to provide for the convenient replacement of the arts thereof and at the same time to prot uce a truck side frame, which may be adapted for use on all classes of cars; to produce my improved side frame of a single arched design without weakening or impairing the strength thereof and without exceeding the standard dimensions and at the same time provide space for the heaviest bolster and spring; to provide improved means for supporting the bolster in connection with the side frame; to provide my improved frame with integrally formed bearing boxes, said boxes being so constructed as to permit of the removal therefrom of the bearing brasses and axle spindles and to produce other improvements, the details of which will be more fully pointed out hereinafter. These objects I accomplish in the manner illustrated 1n the accompanying drawing, in which:

Figure 1 is a side elevation of a truck having my improved side frame and showing a portion of the latter broken away for the sake of convenience in illustration, Fig. 2 is a plan View of the saine, Fig. 3 is a sectional view on line -m of Fig. 1, Fig. 4 is an enlarged transverse section through one of the boxings, the same being taken on two planes as shown by line y-y of Fig. 2, Fig. 5 is a side elevation of one of the boxings, and, Fig. 6 is an end elevation of one of the boxings showing a modified construction and arrangement of door therefor.

Similar numerals refer to similar parts throughout the several views.

1 represents my improved side frame, the body of which as indicated in the drawing, comprises a straight horizontal top portion la and an arched lower portion, the latter comprising a central horizontal bottom )ortion 1b and inclined members 1 lea ing Specification of Letters Patent.

therefrom to the ends of the frame. The frame members thus described are of substantially L-shape in cross section and the central portion of the frame is closed on its outer side, with the exception of an opening 2 which is formed therein for the sake of decreasing thc weight of the casting. On opposite sides of the center of the length of the frame, I provide inwardly projecting verti al flanges 3, which in conjunction with the inwardly ln'ojecting tlauges of the top and bottom frame members, serve to form a central frame pocket on the inner side of the frame, this pocket being adapted to receive the end of a bolster 4, which projects into the upper end portion of the pocket and bears upon the upper one of a plurality of longitudinally disposed arched or curved spring bars 5, which are arranged one upon the other. the lower spring niember bearing in the bottom of said frame pocket and extending between the ribs 3.

In the construction of the upper and lower central portions of the frame l, I form the inturned horizontal tianges thereof, with oppositely located pin bearing openings 6, in which bear the ends of a bolster pin T, the latter passing through and fixed in oppositely located openings S in the end portion of the bolster 4. It will thus be seen that the spring members 5 are arranged between the vertical wall of the frame and said pin 7.

In producing the frame 1, I form integrally with each end thereof, an axle or spindle bearing box 9. Ordinarily, car jouinal boxes are formed with an upper side opening and lid therefor, but for reasons hereinafter .set forth,I forni the upper sides of my journal boxes closed and provide a doorway and swinging door therefor either in the side or bottom of the box, the said doorway or opening connecting with the lusual hub opening 9, In the drawings, with the exception of that shown in Fig. G, I have shown this door and doot-waY at the side of the box and the door which is indicated at 10, has its upper portion suitably hinged above the doorway as indicated at 11, the lower portion of the door heilig formed with two separated projecting lugs 12, which when the door is in a closed position, embrace opposite ends of a lug 13 which projects from the box 9 below the doorway.

In order to provide a desirable form of fastening for the door l0, I employ two substantially hook-shaped bolts er locking members 1l, the hoot; ends of which are adapted to pass through openings in the lugs l! shown in dotted linesl iu Fig. fi and into sockets 1&3 in the ends o' the lng ill.

for said springs. It will also he observed that the advantages mentioned. are aecomplisln-d in conjunction `with a single arch frame and that` this` single arch .trame is ot` a construction which not only prtnides the U The longer arms of these hook members ll t extend toward each other and are surrounded and connected by a coiled spring- 15;.

It will bc observed that the ontei sides` of the lugs 12 are inclined and that the honlt members 1l are in contact with these iiiclined lug .sides` being held iii this posii tion by the tension of the spring 15. Assuming that the door is locked or that the hooi; ends of the bolts are iii engagement with the sockets 12j ol' the lug t3, the method of unlocking the saine or withdrawing said bolts from said sockets, consists in swinging the spring 15 and the longer arms 'of the bolts upward, resulting through the engagement of the hook members of the bolts with the inclined sides of the lugs 12, in forcing the hook terminations of said bolts outward until they are disengaged from the lug 13.

In Fig. 4 of the drawing` I have shown the car wheel axle spindle in cross section i at 1G and above this spindle1 the usual form of bearing block or brass 17 which is siii'- mouiited by a follower 18. This bearing` brass has a lateral extension 1T which engages an internal wing 10"* on one side of the upper portion of the box 9 and on the opposite side said brass is likewise provided with a projection or extension 17h which engages a recess in an inwardly projecting arm 10a of the door 10, when the latter is in a closed position, the brass bearing member being r thus properly retained in contact with tlie upper side of the spindle. This method of supporting the bearing biasses is, however, well known and does not form an essential part of my invention.

In Fig. 6 of the drawing, I have shown a slight modification in the construction of the box, which consists in forn'iing the door opening iii the bottom of the box and providing a hinged door therefor as shown at 19. It will be understood that the same coiistruction of fastening device may be eniployed as that described for the door l0.

In the construction of side frame which I have described, it. will be observed that the bers of the frame without the necessity of I extending the spring seat beyond the sides of the frame body and without the necessity of providing a` specially formed seat for the spring, inasmuch as the bottoni flange of the lower frame member, serves as a seat required strength a nl gives space ior the support ofthe heaviest holsters and springs` in a trncl-z frame in which the standard dimen-ions are not exceeded. The emplo \jment ol' the single arch trame is of especial value iii providing a frame of reduced height which is desirable for they reason that a greatei'fspace is provided between the frames and t'iaclis and between the frames and cars. thereby facilitating the employment ot' bottom dump cars without interference by the truclc frames.

I ain aware that it is not broadly new to provide an integrally formed truck frame and journal boxes, but the diiiicnlty usually experienced in such constructions lies in the inability to disconnect the axle bearing spiir dles from the journal boxes.

The construction which I have shown and described provides for a door which may be located at the side oi' bottom of the box iiistead of providing the usual upper side opening and lid therefor.

Assuming that my journal boxes are equipped with the side doors such as those indicated at 10, it is obvious that when the truck frame has been jacked up to a suit'r cient height. said side doors may be opened to permit of the lateral withdrawal of they axle. It will also be understood that in the't opening of the side door, the engagement of the arm 10'il and brass 17, will be released," thus providing means for readily removing brasses from the boxes or inserting new ones. It is obvious that this removal may be accomplished by the employment of a bottom door such as that indicated at 19.

Another advantage of my construction, lies in the fact that by providing the bearing openings in the upper and lower portions of the frame, distant bearings are provided for the bolster guide pin, which obviates the necessity or desirability of employing the usual tie connections between the frames to retain the frames in their relative positions with reference to the bolster. This construction also permits of doing away with the usual column guides between the upper and lower bolster members.

That I claim, is:

1. truck side frame and journal box comprising but two separately formed elements which consist in a side frame body having a journal box body cast integral therewith and a nic able door for said box adapted to permit the lateral removal of the axle and cooperating bearings.
